aFe Power Magnum FORCE Stage-2 Si Pro 5R Cold Air Intake for BMW 228i/320i/328i/428i 2012-2018 (L4-2.0L)

Fits select 2012-2018 BMW 228i, 320i, 328i, and 428i (L4-2.0L Turbo N20) including xDrive and Gran Coupe models.

The aFe Power Magnum FORCE Stage-2 Si intake system provides a significant performance upgrade by replacing your BMW's restrictive factory air box with a high-flow, sealed system. This system utilizes a cross-linked polypropylene rotomolded plastic air box that houses a built-in ram scoop to capture fresh, cold air from outside the engine bay. By isolating the intake charge from engine heat, the Stage-2 Si improves combustion efficiency and throttle response.

Equipped with the Pro 5R air filter, this system features five layers of progressive cotton gauze media for maximum airflow and filtration. The precision-engineered rotomolded intake tube is designed to maximize airflow velocity, resulting in a documented 42% gain in CFM flow compared to the stock intake. This bolt-on upgrade provides a factory-style fit and finish while delivering a more aggressive intake note under load.
